1. Three workers can do a job in 12 days. Two of the workers work twice as fast as the third. How long would it take one of the faster workers to do the job himself ?
- A. 24
- B. 24
- C. 24
- D. 24
Answer: Option B
Explanation:
1 faster person = 2 slower person
so , 2 faster + one slower = 5 slower person
5 slower person can do the work in 12 days
1 ,, ,, ,, ,, 12X5 days = 60 days
As, 2 slower = 1 faster then,
1 faster person can do the work in 60/2 = 30 days .
so , 2 faster + one slower = 5 slower person
5 slower person can do the work in 12 days
1 ,, ,, ,, ,, 12X5 days = 60 days
As, 2 slower = 1 faster then,
1 faster person can do the work in 60/2 = 30 days .
